New HPS7 mutation discovered

Researchers in the United Kingdom have discovered a new mutation on the HPS7 gene. Previously, there was only one documented patient with HPS7. The new mutation was found in a patient with albinism and a bleeding history who was not diagnosed with HPS until she was 77 years old. She did have an extensive bleeding history and a Crohn’s diagnosis. She did not have any evidence of pulmonary fibrosis. 

How sad is it that this woman had so many HPS complications her entire life, yet never got an HPS diagnosis. We don’t think that type 7 causes pulmonary fibrosis, but it is not just the HPSers with gene types that cause pulmonary fibrosis who endure a lot. 

I also read another medical article today about someone diagnosed with HPS type 5 at 92! Let me say that again, 92! 

It is a lesson to say there are probably many people out there with HPS who are never diagnosed. It is a lesson to show that one should never use age as an exclusion for suspecting HPS. It’s also a lesson about how organizations serving people with albinism should help to educate their memberships about HPS. Even some of the “old timers” might benefit.

Nobody likes rejection

Me posing for a photo with Finley. This is my swollen steroid face. Thankfully, it is starting to go down.


Rejection – it’s a word I’m hard pressed to find a good context for – and in transplant land, it certainly isn’t a good thing, but perhaps it’s a constant companion. Once you get an organ that you weren’t born with, your body is intent on seeing this life-saving gift as a foreign invader it must destroy. It’s a battle that is constantly going on inside you, and it’s a battle you and your doctors constantly fight. The only good news is medicine has created a number of weapons to hold rejection at bay.



In June I had my first setback because of acute cellular rejection. They tell me it’s the good kind of rejection to have because it is treatable with an onslaught of steroids and medication adjustments. Oh goodie!



It was amazing how quickly it came on, and really brought home how important it is to do those vitals and spirometry every day. When I thought I might be in trouble, I had m…

Planning for Armageddon

Sometime in January I had a transplant clinic appointment. I can’t exactly remember the date now, but I remember the appointment very well. It was the beginning of what could have been the end.



I did the usual tests – spirometry, a six-minute walk etc. I was now not just on eight to 10 liters of oxygen. I needed 10 liters of oxygen pretty much all the time; even to walk the maybe 15 to 20 feet to my bathroom. To go for a slow walk required 15 liters.



The funny thing about increasing oxygen, especially when it happens over years as it did for me, is that you adjust to it. It just becomes your normal. You might get annoyed by it, but somehow it becomes this thing in your life that just is there. So, although I was clearly very sick at this stage, I didn’t feel sick. I felt tired a lot, but not sick. I didn’t feel pain (thankfully). I didn’t feel weak (even though I needed a lot of help with household activities so clearly I was). I just adjusted. I coped with the waiting for a new lung …

The next generation with Hermansky-Pudlak Syndrome

I'm so behind on posting about the trip to Puerto Rico. Since the episode of Mystery Diagnosis on Hermansky-Pudlak Syndrome ran right after we got home, it's been a little busy. These, however, are my favorite pictures from Puerto Rico. I know, not pretty senery etc - but these little guys and gals inspire me. They are the next generation of folks with HPS, and if we keep up the hard work, they will live better lives because of it. They motivate me.
